Social Networking for the Antisocial

I already have a Myspace account I use for lurking on other people's sites so I established a Facebook account. I used my real information on the off chance that one day some long lost friend will contact me. It is very easy to establish a boring page on Facebook. I think Facebook is a little too restrictive with their privacy controls. There's not much you can see on someone's profile unless you become their "friend," which is more than I want to do with people I may know only distantly. In this way the more free-wheeling Myspace system is better. I also am puzzled by the concept of "poking" on Facebook. I needed to do an experiment to see how it works and even then didn't see the point of poking.
